Task Two New Line error

[WA64]

I am receiving the following error in the TaskTwoTests file even before I try implementing a listener specifically with "kafkaProducer.send(transactionLine);":

"java.lang.NumberFormatException: For input string: "122.86
5"
at java.base/jdk.internal.math.FloatingDecimal.readJavaFormatString([FloatingDecimal.java:2054](..."

The data file this is using has 122.86 and 5 separated by a new line character. It had no issues processing the numbers beforehand separated by a comma. The yaml file was actually blank when I downloaded the zip so a used the solution provided in the other post (Thank you for that). Am I meant to fix this somehow in my listener class, or could there be an error in my configuration files? I am running VS Code on Windows 11.

It looks like transactionline from this loop in the test:

for (String transactionLine : transactionLines){

is printing out the whole data file as a string, rather than separating each line

Make sure that you're properly handling newlines and commas and that the data is split correctly for processing.

[puchakayala-jeevan]

for (String transactionLine : transactionLines) {
// Trim any unwanted spaces or newline characters and split the line by commas
transactionLine = transactionLine.trim();
String[] parts = transactionLine.split("\n");

// Check if there are exactly two parts
if (parts.length == 2) {
    try {
        double value1 = Double.parseDouble(parts[0].trim());
        double value2 = Double.parseDouble(parts[1].trim());
        // Process the values (e.g., sending them to the producer)
        kafkaProducer.send(transactionLine);
    } catch (NumberFormatException e) {
        System.out.println("Invalid number format: " + transactionLine);
    }
} else {
    System.out.println("Unexpected data format: " + transactionLine);
}

}

The provided code snippet seems to be part of a Java program that processes a string split into parts. However, there are a couple of issues that need to be addressed. Here is a revised version of the code:

// Check if there are exactly two parts
if (parts.length == 2) {
    try {
        double value1 = Double.parseDouble(parts[0].trim());
        double value2 = Double.parseDouble(parts[1].trim());
        // Create the transaction line (assuming you want to format it somehow)
        String transactionLine = value1 + "," + value2; // Adjust according to your needs
        // Process the values (e.g., sending them to the producer)
        kafkaProducer.send(transactionLine);
    } catch (NumberFormatException e) {
        System.out.println("Invalid number format: " + transactionLine);
    }
} else {
    System.out.println("Unexpected data format: " + transactionLine);
}

Key Changes:

1. Transaction Line Creation: Make sure the transactionLine is correctly defined before it is sent to the kafkaProducer. In the above code, it's created by concatenating value1 and value2. Adjust this as necessary to match the expected format for your Kafka producer.

2. Handling transactionLine: The initial reference to transactionLine in the catch block might cause an issue if it's not defined in the scope of the try block. Ensure that transactionLine is constructed before it’s used, as shown.

3. Consider Null or Empty Parts: If there's a chance that parts could be null or empty, you might want to add additional checks to handle those cases gracefully.

This should resolve any issues with the code snippet provided.
